PI49FCT32805
Description
PericomSemiconductor’sPI49FCT32805isafastspeed,lowskew,
fast slew rate, and low propagation delay for most computing and
communication applications.
The devices are non-inverting drivers. The outputs are configured
into 2 groups of 1-in, 5-out with independent output enable. Group
B has an extra MON output. Excellent output signals to power and
ground ratio minimize power and ground noise, and also improves
output performance.
PI49FCT32805 integrate series damping resistors on all outputs.
Features
Low output skew: <270ps
Switching frequency of 133 MHz
Fast output rise/fall time <1.5ns
Low propagation delay <3.0ns
Low input capacitance <6.0pF
Balanced CMOS outputs
Industrial Temperature: –40°C to +85°C
3.3V ±10% operation
Packaging: (Pb-free & Green Available)
– 20-pin 300-mil wide SOIC (S)
– 20-pin 150-mil wide QSOP (Q)
– 20-pin 209-mil wide SSOP (H)
